A group consequence one person controls is a dependent group contingency. The whole group receives or loses the programmed outcome based on a selected person or subgroup's performance. This structure can expose the selected member to attention, pressure, blame, or sabotage. Before use, define selection, visibility, consent and assent, accessible criteria, individual supports, peer monitoring, an immediate stop route, and alternatives that avoid placing group access on one person.
Review a group consequence one person controls
Ask how the person is selected, whether identity is known, which response counts, what the group receives, and what happens after absence, withdrawal, health needs, missed opportunities, or staff error. A supposedly random selection still needs a valid and auditable method.
Examine social consequences
The group-contingency analysis explains that group members may deliver added social consequences to influence performance. Those unprogrammed consequences can include encouragement, monitoring, blame, exclusion, or coercion. Observe and ask about them directly.
Consider a different arrangement
An independent rule can let each member control their own outcome. An interdependent rule can use an aggregate threshold that avoids naming one person, though it still creates shared risk. Individualized support or a universal noncontingent activity may fit better when group linkage adds little value.
Keep ethical and access gates
The Ethics Code addresses client involvement, consent and assent when applicable, confidentiality, risk, and evaluation. The ASHA AAC guidance supports continuous communication access. Protect the selected person's identity and messages as the setting and governing requirements allow.
A practical example
Miles is selected as the dependent member for a team cleanup outcome. During the first trial, peers repeatedly remind Miles and one blocks access to another activity. Miles selects stop on AAC. Staff end the arrangement, deliver the ordinary break, document peer behavior, and move to individual cleanup choices.
Questions families can use
Why must group access depend on one member? Does the person know and agree? Is identity visible? What peer effects are measured? Which alternative reduces shared risk? What signal stops the arrangement?
